New Mats - Suggestions & Sources

Evening, any and all.

I could be in the market soon for around 3,000sq feet of matting.
So, pricing up options on judo mats, 40mm jigsaw, foam on a roll etc. Options, sources (anyone used any firms from AliBaba ?), experiences etc greatly appreciated.

Cheers,
The Hands
